Description
(54) СПОСОБ ИСПЫТАНИЙ МАТЕРИАЛОВ НА РАСТЯЖЕНИЕ(54) METHOD OF TESTING MATERIALS FOR STRETCHING
1one
Изобретение относитс к испытатеп ной технике, а именно, к способам испытаний материалов на раст жение.The invention relates to a test technique, namely, to methods for testing materials for stretching.
Известен способ испытаний материалов на раст жение, заключающийс в том, что в испытательном устройстве нагружают вераст жвмый элетлент усилием, превыша юпшм усилие разрушени образца материала , затем в том же испытательном устрой стве нагружают испытуемый образеп и определ ют его прочность 1.The method of testing materials for stretching is known, which means that the test device loads the force of the eleventh force exceeding the force of destruction of the specimen of the material, then the test piece is loaded in the same test device and its strength is determined 1.
Однако способ обладает недостаточной точностью определени прочности.However, the method has insufficient accuracy in determining strength.
Цель изобретени - повышение точноо- 15 ти определ« ни прочности путем учета деформации испытательшэго устройства The purpose of the invention is to increase the accuracy of the 15
Указанна цель достигаетс тем, что в процессе нагружени нераст жимого элемента регистрируют диаграмму усилие -20 дефо кигащЕЯ испытательного устройства и вычитают ее из диаграммы усилие - деформаци , которую регистрируют при вопытании образца.This goal is achieved by the fact that, during the loading of an inextensible element, a stress diagram of -20 deflection test device is recorded and subtracted from the stress-strain diagram, which is recorded when the specimen is tested.
На чертеже изображено устройство дл осуществлени способа.The drawing shows a device for implementing the method.
Устройство содержит нагружающие элементы в виде т нущего штока 1 и опорной трубы 2,- размещенные, например, в криостате 3, динамометр 4. и деформометр 5, электрически св занные с регис1 рирующим прибором 6, например самопио а.&л. Деформометр 5 св зан электрически с электронным блоком 7, который в свою очередь электрически св зан с регистрирующим прибором 6. Динамометр 4 электр чески св зан с регистрирующим прибором 6 как непосредственно, так и через электронный блок 7.The device contains loading elements in the form of a heavy rod 1 and a supporting pipe 2, placed, for example, in a cryostat 3, a dynamometer 4. and a deformometer 5, electrically connected with a recording device 6, such as a self-amplifier. The deformometer 5 is electrically connected to the electronic unit 7, which in turn is electrically connected to the recording device 6. The dynamometer 4 is electrically connected to the recording device 6 both directly and through the electronic unit 7.
Способ реализуете следующим образом .The method is implemented as follows.
Нераст жимый элемент (не показан) размещают между нагружающими элемецтамн испытательного устройства.A non-expandable element (not shown) is placed between the load element of the test device.
